Hello Gurus, Is it possible to prepare a CSV file and run a script that will get the the information of those who have access to a mailbox for hundreds of mailboxes in one go? Please advise. Thanks a lot.Never stop learning

What do you want the .csv to look like? There could be multiple permission assignments per user, and multiple users accesses per mailbox. Exporting a muilti-valued property to a .csv field can get ugly.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "
